Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504982, here are decompositions:
- 31 + 31504951 = 31504982
- 73 + 31504909 = 31504982
- 79 + 31504903 = 31504982
- 109 + 31504873 = 31504982
- 163 + 31504819 = 31504982
- 181 + 31504801 = 31504982
- 199 + 31504783 = 31504982
- 331 + 31504651 = 31504982
Showing the first eight; more decompositions exist.
